Circuit board instructions
1 torch adopts advanced constant voltage and constant current technology, which can effectively solve the requirement of constant voltage and constant current for LED torch.
2. Special tips: a. Do not use it over pressure, and the voltage should not exceed 4.2V B. The battery is facing forward, do not set it in reverse, otherwise it will burn plate c. Pay attention to controlling the change of flashlight temperature to ensure heat dissipation d. Do not open the circuit board for non-professionals.
3. Warranty description: no longer covered by warranty after opening or handling the circuit board.
1. Features of lithium battery: the charging method of lithium battery is completely different from that of mobile phone battery; Lithium battery has no memory, and can be charged at any time, and should not be overcharged or overdischarged.
